Product Description

Cast Alnico Magnet

Product Name: 
Alnico Magnets, Alumimum-Nickel-Cobalt Magnets, Cast Alnico Magnets, Sintered Alnico Magnets.

Features:
An ideal material in high temperature applications, which has high operating temperature up to 550°C and above,  with excellent corrosion resistance. They can be partially demagnetized if they come in contact with other ferrous materials, special care is required during handling and storing.

Usually cast and grinded during production, they are available in various grades depending on its application. Others such as sintered Alnico have lower magnetic properties but offer higher mechanical characteristics
 
Characteristics 
Compact crystal, high intensity
Good chemistry stability, strong anti-corrosion
Even elements, excellent and magnetic performance
Excellent temperature stability
Highest usage temperature reach 550°C

Two kinds of Alnico Magnet production methods:
*Cast Alnico can be made into many sizes and shapes; 
*Sintered Alnico is usually restricted to smaller sizes.

However, both process lead themselves to complex geometries and configuration.
Standard Sintered Alnico has tighter dimensional tolerances due to its processing. It also has slightly lower magnetic properties, but better mechanical strength than Cast Alnico products.
 
Cast Alnico can be made into intricate and complex shapes, which is not possible with other magnetic materials. It is high magnetic flux density, resistance to corrosion and excellent temperature stability, the maximum working temperature up to 600°C.
 
Cast Alnico magnet is widely used in all kinds of sensors and meters, electronics, instruments, medical instruments, teaching, automobile, aviation, martial and other applic- ations.
 
So Cast Alnico magnet is much popular than Sintered Alnico magnets.
